This was our first trip since she lost her sight due to a cerebral bleed. She tried to use a Travel John but that didn't work out. She agreed to wear an Attends but, three hours into the trip, she said she wouldn't use it and kept asking to stop at a restroom. We got lucky at a Visitor Center in Virginia. The attendant prevented others from entering the Ladies Room so that I could accompany her. I can't depend on this happening again and was wondering if anyone could suggest anything? Thanks in advance for any responses.
Medical facilities typically have unisex bathrooms, and in my experience they're cleaner than a lot of other public bathrooms. You could locate hospitals and medical complexes along your route, contact them beforehand to confirm that they do have unisex bathrooms, and go with your wife to help her.
I'm so sorry to learn of her loss of sight. You're both very strong and brave to find a way to continue with your travels after this event.
